the study of motion without considering the forces causing the motion.
Displacement
the change in position of an object. It is a vector quantity, meaning it has both magnitude and direction.
Velocity
the rate at which an object's displacement changes over time. It is a vector quantity.
Acceleration
the rate at which an object's velocity changes over time. It is a vector quantity.
Speed
the rate at which an object travels over a distance. It is a scalar quantity, meaning it only has magnitude and no direction.
Scalar quantity
a quantity that has only magnitude and no direction, such as speed or mass.
Vector quantity
a quantity that has both magnitude and direction, such as velocity or force.
Position
the location of an object in space. It is often measured relative to a reference point.
Time
a dimension in which events occur in a sequence. It is often measured in seconds.
Distance
the total length traveled by an object, regardless of direction. It is a scalar quantity.
Displacement-time graph
a graph that shows the change in an object's displacement over time.
Velocity-time graph
a graph that shows the change in an object's velocity over time.
Acceleration-time graph
a graph that shows the change in an object's acceleration over time.
Uniform motion
when an object travels with a constant velocity (i.e. no acceleration).
Uniformly accelerated motion
when an object accelerates at a constant rate.
